The bps with packet is the same as the baud rate. With other modes that have different levels, the signalling rate (the baud rate) can have more than one bit sent per baud. The fastest baud rate that Pactor uses is 200 baud, but the bps rate is many times faster with P2 and P3. The speed of co

So is 1200 baud = 1200 bps and 1200 bps (1200 / 8) = 120 cps? If so then 120 cps (120 / 6) = 20 wps X 60 sec. or 1200 WPM. That's over 1.5 pages per minute. (Page = 72-76 characters X 60 - 66 lines per page.) Walt/K5YFW Chris Jewell wrote: > Walt DuBose writes: > > How can 1200 baud = 1320

How can 1200 baud = 1320 WPM? In the case of AX.25 baud=bps since a mark-space=one bit. An 8 bit ASCII character with start and stop bits would be 10 bps so 1200 bps=120 CPS. If a word is 6 characters, then 120 CPS = 20 WPM which we know is too slow. As far as a mode using a VariCode, the WPM
